I had a frozen pipe so called a few places before Princeton air and plumbing. They were the only ones able to send me someone the same day which was a Sunday! Mike was very professional and effective and luckily was able to thaw the pipe in 20 min!
Smart, nice, responsible. Great job with our new heat pimp.
Great service as expected.
Sink was leaking after 1st plumbers fix. To many short cuts. Error was corrected and the sink is no longer leaking. Lynn
I had Dominic help with my AC/heat pump for a tune up. He was very knowledgeable and personable. ๐Ÿ˜
Latrell was wonderful! Great service and knowledgable.
Knowledgeable, professional, thorough and honest!
The HVAC system has been just installed today, therefore, I am not ready for review for the system.
However, the Installation groups are excellent.
Neim was really professional and explained everything to me and he took his time
Tanzil Ali was the best tech I've ever dealt with. I strongly suggest anyone have your unit serviced by him. He was professional clean and did the job amazing. I strongly suggest recommending him.
I am extremely grateful to Princeton Sir Conditioner for the service they provided with Mr. Gaines. He resolved the issue with the unit. Very diligent. It seems the problem stemmed from the unitโ€™s age. They couldnโ€™t find the replacement part at the time. The cold in my house was unbearable. The technician, in his search, found something that could be adjusted for the unit, with had been installed 10 years prior. He located it two hours away and returned with it. It took him a considerable amount of time to adjust it, but he succeeded. He informed me that The PAC finally had found the correct part, and he would return next day to make the necessary replacement. He emphasized tha The PAC wanted the service to be of the highest quality, resolving the issues and ensuring the unit was installed to the required standard. He also assured me that I would have the perfect temperature in my home. They provided me with excellent service!!! Great job and service!!!
Ryan G. arrived to perform regular A/C maintenance and determined the drain pipes leading from the condensor coil into the sump were clogged and in need of replacement. He performed the work in timely fashion at a reasonable price and also took the time to provide some useful advice. This is the second time Ryan has performed service in my home and I find him to be a helpful and conscientious professional.
Jose and his crew worked all day (11 hours at least) to remove old and install a new A/C and furnace and completed the job and clean/up in one day. Professional and courteous crew and came out quickly.
Brian, our electrician was fantastic- and deserves a 10 star rating. This rating is deceiving though- because I have been asked to rate the technician and not the company.

Unfortunately, the rest of our experience with Princeton Air has been very sub par- and I would not recommend using them.

Although our situation was considered a โ€˜fire hazardโ€™ and โ€˜emergencyโ€™, it took multiple telephone calls throughout multiple weeks to Princeton Air to get the work completed. (A township permit is necessary for the work we needed completed- but the township acknowledged that in cases like ours, the work is done immediately and the permit is issued retroactively in order to diffuse a dangerous situation.)

Then, to completely finish the work, it took additional days- unfortunate, but expected. The TRULY DISSATISFYING part was the lack of truthful
communication from the scheduling department- and its service manager- who, although promised, has still not called to discuss the situation.

For these reasons, I will not recommend Princeton Air- despite their electrician, Brian, being terrific, highly capable and very personable.
No issues and work was done in one day. They had easy payment plans to pick from.
Technician came on timely manner and did an excellent job diagnosing the problem with our furnace.
Jason from Princeton AC was very professional. I explained my situation and he fully understood my issue. After diagnosing my problem Jason provided me with an estimate and explanation of the job required.
Great service call
I've been using Princeton Air since they were Weltman home services. They were punctual, professional, and friendly. They were very efficient in the work done a few weeks ago.
Brandon came last week to do the spring service. He was on time, polite and efficient
Since it is a new system not much needed to be done
Jason Muniz was terrific in pointing out a potential problem for us. His explanation was clear and he was not alarming.
Jason was on time and courteous, the kind of professional who we like to have take care of our home,
Thanks so much for the EXCELLENT service from Dominic . He was GREAT!! Explained everything to us in a professional and friendly manner!! Great guy!!
Excellent technician (Naim) who checked everything, replaced air filter (slot to place it in has always been a problem) and identified potential alternative placement for air filter which would be lower cost fix. Most important is that he explained each step of what he was doing and finding and my options moving forward.
Quickly found, evaluated and repaired the problem. . Very helpful. Larry
Dominick was on time, very friendly and explained things so I could understand. I am going to ask for him every time I need service
